Evaluation of three mainstream Web development skills: PHP

PHP: Why does PersonalHomePagePHP appear? It is a skill staff looking forward to using a quick way to make small use of his personal homepage. Php is displayed when he cannot receive a message, which enables a person to run PHP: Personal HomePage

Why does PHP appear? It is a skill staff looking forward to using a quick way to make small use of his personal homepage. When he was unable to accept the attack, he showed php, which enables a person to implement a lightweight Web application in a variety of control systems. So in just a few years, php has updated its version quickly and found Apache, a great partner in the GNU world. This finally gives php the foundation to run in the best environment. at the same time, because both products are open-source products, so you can apply their source code to combine these two products in the most perfect way, just like a product. I personally think that php is a powerful tool for free software on the web application platform. If php is not displayed, there will also be many people who think that free software represents high-tech requests to developers, hard-to-remember code, and complex tools ..... php enables a basic application employee to quickly learn and utilize the user's needs in a very short time.

How does one say php? If ASP is a COM, php is more accurate. it can be said that php is a pure Script translator. This is also a major reason why php is upgraded from 3 to 4. in version 4, it overwrites the syntax analyzer, thus accelerating the overall efficiency of php. In addition, you will understand why php must re-compile with the lib library of the corresponding system when it needs to support this or that expansion function. Because it is an authentic "translator", it translates scripts into functions to be executed and then implements them. external expansion cannot be carried out by some "dynamic loading" methods, therefore, only static code can be compiled into php (except for windows ).

Strong:

1. a development language capable of fast learning, cross-platform, and good database interaction. ASP is a cross-platform talent that cannot match it, and it is a kind of talent that allows Unix/Linux to have a development language comparable to ASP. Simple syntax, easy to write, and now there are a large number of books on the market, while a large number of codes on the Internet can be shared, A beginner wants to learn more about development under "Advanced Unix.

2. work closely with Apache and other extended libraries. Php and Apache can be combined by static encoding, and can be combined with other extended libraries (except for Windows ). The biggest benefit of this method is to maximize the utilization of cpu time and memory, and at the same time, it is extremely effective to take advantage of apache's high-performance throughput. At the same time, the external expansion is also static connection, thus achieving the fastest operation speed. Because this method is also applied to the database interface, the local call is applied, which also gives the database the best performance.

3. good security. Since php code is open, its code has been tested by many engineers. at the same time, its method of coding with apache can also give it mobile security settings. So far, php has been recognized as a secure performance.

Weak:
